Williams' Panasonic Wild Knights lost 25-22 to NTT Communications Shining Arcs, where another former All Black in Isaac Ross plays, a big result in an exciting round two of competition.
Playing alongside Mike Delany, Williams played a full 80 minutes, and with the addition of the former All Blacks centre, last season's runners up were expected to be too strong for NTT, who recorded their first win.
The Knights looked to be cruising to a comfortable victory when they extended their 17-3 halftime lead to a comfortable 22-3 cushion early in the second half, with Akihito Yamada, Tadasuke Nishihara and Tetsuya Shitara scoring tries.
But while Williams was arguably the star attraction, another giant in Alesana Tuilagi stole the show, when he contributed one of NTT's three late tries that allowed them to win the match.
The match of the weekend came when defending champions Suntory Sungoliath were given a torrid examination by newly promoted Kyuden Voltex, with the minnows outscoring the Japanese giants five tries to four, before the boot of former Waratah Peter Hewat gave Suntory a 34-29 win.
